Quantifying source and dynamics of acidic pollution in a coastal acid sulphate soil area por Phong, N.D., To Phuc Tuong, Phu, N.D., Nang, N.D., Hoanh, Chu Thai

“…This study involved a long-term (2001-2006), large-scale canal water quality monitoring network (87 locations) and a field experiment at nine sites to quantify the dynamic variability of acidic pollution and its source in a coastal area with ASS in the Mekong River Delta of Vietnam. Widespread acidic pollution (pH <5) of surface water occurred at the beginning of the rainy season, while pH of the canal water remained high (7-8) at the end of the rainy season and during the dry season. …”
